You can technically use pretty much any smoking device to smoke Crack. The issue here is that you're not "burning" it in the same way that you would Tobacco, Cannabis or, if you're into decidedly negative psychedelic experiences, Salvia Divinorum. It starts as a "rock" and as heat is applied it will turn into what I believe you would call an "oil" (please correct me if I'm wrong drug nerds

). At any rate, in the process of sublimation/vaporization it will turn into a liquid. This is why steel wool or "chore" is used in the vaporization of Cocaine.
The "liquid" gets trapped in the the steel wool in its liquid form allowing for it to vaporize without falling through the pipe. So the answer would be, you can use a chillum if it has steel wool inserted in the bowl. You could use any pipe, but straight, short pipes are favored for a couple of reasons. First, the potency of the Cocaine vapor has a tendency to lose potency the longer it must travel from the point of vaporization to your lungs. Secondly, straight pipes are favored due to the ease of scraping them for the remnants of Cocaine residue, which is then resmoked.
You will typically perform this process at least a dozen times over the course of your experience before taking to the carpet to look for more Crack... whether you like it or not. Say no to crack kids. Listen to Keif, do dope instead. Sorry Nancy
I have a vison of a Keif Richards puppet, operated by me in a falsetto, imitation-Mary Poppins British Accent telling kids to do my favorite drugs, teaching them about proper injection technique and safety, how to cop in the ghetto without getting shanked and many other important life lessons. We would also have a Honey Badger puppet who I will always chastise at the end of each episode for stealing my dope.
"Badger, you unholy motherfucker!!!!! I'll fucking kill you!!!. See you next Saturday little ones, every Saturday morning at 9, 8 central!"
I'm going to Hell.
